Question

Answer really quickly please

Answer 1

Answer:

a. 65:195

b. A

Step-by-step explanation:

for part a:  

1:3 means there are 1+3=4 parts

so 260/4=65

so the 1 is 65 and the 3 is 3(65)=195 so

a. 65:195

for part a.

3:5 is equal to 1:n

so divide 3:5 by 3 on both side so

3/3 : 5/3 =

1:5/3

b. A

Answer 2

Answer:

see explanation

Step-by-step explanation:

(a) Add the parts of the ratio, 1 + 3 = 4 parts

Divide 260 by 4 to find the value of one part of the ratio.

260 ÷ 4 = 65 ← value of 1 part of the ratio, thus

3 parts = 3 × 65 = 195

260 in the ratio 1 : 3 = 65 : 195

(b)

Given

3 : 5 ← divide both parts of the ratio by 3

$\frac{3}{3}$ : $\frac{5}{3}$ = 1 : $\frac{5}{3}$ → A
